It's actually surprising how long the prejudices persist.
Prefab houses - there are also ones made of bricks (how do they hold up regarding value retention, remodeling, ???)
Prefab houses come in all kinds of quality levels - from catalog models to individual architect solutions.
The same applies, by the way, to 'solidly' built ones.
Solid... is aerated concrete solid? Or such a highly porous brick - ever used a rotary hammer on it?
And how should prefab element ceilings or prefab roof trusses be rated (here someone 'solidly' glued their house from aerated concrete and had a larger carpentry company manufacture the roof truss in the workshop and put it on the house - roof is in place and watertight within one day).
There are reasons why some people prefer to build 'solidly,' others prefer timber frame construction, and yet others prefer 'solid wood' - does that then count as 'solid' or 'prefab' house? And I have also seen timber frame structures at the construction site that were only assembled and sheathed from individual parts there. Not solid, and definitely not prefab... It also became a nice house, where remodeling later on should not be a problem.
Regarding the popular topic 'construction time': sometimes a prefab house can be occupied faster from the start of planning. Depending on the workload in the factory, weather, degree of prefabrication. But you can't rely on that! Even from the start of construction - it still depends on the workload and availability of all individual trades...
Value retention... is also difficult to answer. High-quality houses always perform better in the local market environment than dilapidated properties; the construction method plays little to no role here. The renovation effort can be significant in both cases, but can also be very low in both cases - this has a significantly greater impact on the achievable purchase price than the construction method.
Durability? Usually not a factor either. The oldest houses in our village all have a masonry base and on top a braced timber frame, filled with straw and clay.
